8 Claims.

This invention pertainsv to trucks, and more Aparticularly to control mechanism for selectively dispensing iluid from the compartments of tank vehicles. l In certain types oi vehicles used for carrying different uids such as different grades of gasolines and oil it is desirable that control m'eans be provided which is operable from a single point to selectively control the liquid dispensed from the various compartments of the truck. This type of mechanism must be easily controlled, and at the same time must be operable to insure delivery oi uid from the compartments under any conditions.

It is therefore an'object of this invention to provide a simple, effective dispensing system for tank vehicles which is operable to selectively dispense liquids from certain tanks of said vehicles.

Another object is to provide control mechanism which is operable under all conditions.

A further object is to provide a system of duid operation for a control system for' tank vehicles..

the invention may consist of certain novel features of commotion and operation as will be,-

more fully described and particularly pointed out in the specication, drawings and claims appended hereto. 1

In the drawings, which illustrate embodiments of the device and wherein like reference characters are used to designate like parts- Figure 1 is a diagrammatic elevation of a tank vehicle dispensing system embodying Athe invention;

Figure 2 is an enlarged end elevation of the control valve for the tank system shown in Figure l;

Figure 3 is an enlarged sectional elevation through the control valve operating means shown in Figure 2 taken at substantially ninety degrees thereto;

Figure 4 is a sectional elevation of a modiiled form of control valve operating means;

Figure 5 is an enlarged fragmentary sectional elevation through a portion of the tank and` the controvalve therefor:

Figures 6 and 7 are sectional views taken on planes indicated 6 6 and 1 1 in Figure 3.

Referring rst o! all more particularly to the constructions shown in Figures 1 to 3 inclusive, the tank I0 of the tank vehicle is sectionalized, beingprovided with any number of tanksv l2, shown three in number, each of which is provided with the control valve I4 welded as at i8 to each tank adjacent the lowest point thereof. Each control valve is provided with a dispensing pipe or conduit I8 running to a suitable place on the vehicle, it being understood that each pipe may run to a common outlet source. The ve- 5 hicle is provided with the usual bucket box or compartment 2li in which the control valve operating mechanism 22 is disposed.

The control valve operating mechanism consists essentially of a casing 24 secured at 26 t0 l0 the platform 28 provided in the bucket box. The casing 24 is closed by means of the; cover plate 30 having the standard 32 provided thereon. An operating handle 34 is pivoted as at 36 to the standard 32 and engages the head 38\of thelrod l5 40. The rod 40 extends through a suitable stuiing box 42 provided in the head 30, and extends downwardly and is secured as at 44 to the head member 46 ported at 48, there being provided a flexible diaphragm or sylphon 50 disposed between 20 the head 46 and the member 52 whereby chambers 54 and 56 are provided, the head 46 being normally urged downwardly by means of the spring 58. The ports 48 are normally closed by means of the valve member normally urged to closed 25 position by means of the spring 62 disposed between the valve member 60 and the head l64 provided on the rod member 40.'

The chamber 54 is in communication through the passage 66 with the chamber 68 through the 30 passage l0, the chamber 68 being normally supplied with a fluid such as oil as through the tting ll. Sleeve 12 is rotatably mounted through the stufling box 14 and is provided with the disk 16, which disk is provided with the aperture 18 adapt- 35 ed to be selectively aligned with channels connected to the various pipes 82 connected to their respective control valves I4. 'Ihe disk 16 is slightly recessed on its side towards the channels 80 but the recessed portion does lnot extend to the 40 aperture 18. The disk has a boss around the aperture 18 in amarmer similar to that shown by disk |8I in Figure 4. Thus the channels 80 are normally in free communication through the recessed portionof the disk with the reservoir 68 45 but when the aperture 18 is aligned with one of the channels 80, the communication between the reservoir and the selected channel 80 is cut ofi'. An aperture 8| is provided between the disk 'I6 and reservoir 68. An operating handle 84 is piv- 50 oted to the yoke 86 as at 88 and has an extension 80 adapted to have contact with the plunger 82 mounted in the sleeve 12, the yoke 86 being secured to the sleeve for operation thereof. The plunger is provided with the ported head s4 stone 55 movable member |52 and the "stationary member |54, the movable member being normally urged into engagement with the iixed member |54 by means of the spring |56, there being provided the slidable member |58 secured to the member |52 and operated through a suitable handle (not shown) pivoted at |60 to the operating member |62 engaging the head |64 of the member |58. It will thus be seen that two chambers are provided as at |66 and |68.

The rotatable member |10 is provided with the operating handle |12, said handle being provided with the pivoted lever |14 adapted -to selectively engage the quadrant |16 for determining the connection between the pipe 82 andthe operating mechanism. The member |14 is urged into engagement with the quadrant by means of the spring |13 and is provided with a rod |15- connected to the sleeve |1| for rotating said sleeve with respect to the member |10. The member |10 is provided with the ported disk |18 rotatably mounted in the chamber 80 and adapted to communicate with the chamber |82 through thechannel |84 and through ports |19 in member 8| and registering ports provided in member |18.

i The disk memberll is formed substantially simvilar to disk 16 of Figure 3. The channels 82 are normally in free communication with the reservoir |82 through the recessed portion of the disk.

4 position by means of the spring |88. The valve member |86 does not close the aligned ports |90 and 9| which are adapted for selective communication between the chamber |80 and the selected pipe82. Y

The control valve I4 is provided with, the casing zoo which is secured to the collar 1oz which is welded to the tank I2 as at I6. The casing 280 is provided with the suitable outlet passage 204 in communication with the outlet pipe |8. The casing is provided adjacent the bottom thereof with the head 206 `secured thereto as at 208, the head being provided with the 'iixed member 2|0. having the sylphon 2|2 disposed therebetween and between the movable member 2 |4. The member 2|4 is provided with the valve stern 2|6 extending upwardly through the spider 2|8 and being provided with the valve member 220 seating on a seat provided on the seat member 222, said member being secured as at 224 to the casing and being of such diameter that the member 222 and its associated mechanism may be readily removed from the casing 200 with the head 206.

A screen 226 is shown disposed on the seat member 222 for preventing foreign matter from causing proper operation of the valve. A spring 228 is provided between the spider and the member 2|4 for. normallyurging the valve to closed position. A hollow tubular member 230 is threaded as at 232 into the head and locked. by

means of the member 234, a drain cap 288 being provided for normally closing the head. The

pipe 82 is tapped into thev head in communical tion with the sylphon.

In operation, when it is desired to discharge liquid from one of the tanks |2, referring first of all to the modification shown in Figures 1,-2, 3 and 5, the selecting handle 84 is moved in a clockwise direction as viewed in Figure 3, causing the member 92 to be depressed against the spring 98 whereby the ports in the member. 94 close communication between the chamber |00 and the port |02. Rotation of the member 84 is had until the selected notch the quadrant |04 is arrived at, at which time the member 84 is engaged in said notch, causing registry between the channel 80 and the port 18. Release of the member 84 permits communication between the chamber |00 and the port |02. Operation oi the handle 34 causes the head 46 to be moved upwardly whereby the liquid trapped in the sylphon will open the valve and ilow through the ports 48 into the chamber 56. Release of the handle 34 causes the liquid trapped in the chamber 56 to flow through the port l|02, the port in the member 94, through the port 18, channel 80, and pipe 82, to the sylphon 2|2, causing the member -2 |4 to move upwardly to open the valve 220, permitting the liquid in the tank 2|2 to iiow through the casing and its dispensing pipe |8. In case the valve 220 becomes stuck or is otherwise renl lease-the fluid pressure and permit closing of the valve 220, the disk 16 is rotated thereby placing the channel 80 in communication with the reservoir at-the same time the aperture 18 is aligned with aperture 8| through the `casing into communication with the reservoir.

A similar operation is had by means of the device shown in Figure 4. 'I'he handle |14 is engaged inits selected notch in' quadrant |16. In selecting operation the member |14 is moved toward the handle |12, causing the member |15 to rotate the members |1| and |8| whereby ports |19 and |11, and |90 and I9| are misaligned, preventing fluid flow during the adjustingvoperation. Themember |62 is then operated to extend `the sylphon |50 against spring |56, causing liquid to be drawn from the chamber |82 through ports |84 and.|19 into the chamber |80, and thence into the sylphon. Release of the member |62 causes the spring |56 to move the liquid trapped in the sylphon through the port |90 to the selected pipe |82, the valve |86 seating' that I do-not wish to be limited by lthe exactembodiments or the device shown which are merely by way 01E-illustration and not limitation, as various and other forms of the device will of course be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
